ELECTRIC PUM PING APPARATUS.

SI ECIFIGATION forming part of Letters-Patent No. 267,710, datedNovember 21, 1882.

Application filed February 17,1882. (NomodeL) V To all whom it mayconcern:

Be it known that we, CHARLES C. PECK and WILLIAM H. CHAPMAN, both ofMiddlebury, in the county of Addison and State of Vermont, have jointlyinvented certain new and useful Improvements in Electric PumpingApparatus, of which the following, taken in connection with theaccompanying drawings, is

a specification.

.10 Our present invention relates to the application of electromagneticforce to the operating ofa diaphtagin-pump; and it consists, first, inthe combination of a receiving-chamber provided with suitable inlet anddischarge valves,

and renderedexpansible and contractible by means of a double-flangedelastic diaphragm, forming a portion oi the walls of said chamber,

'an armature extending across and secured to the top of said chamber,anelectro-magnet so disposed relative to said chamber and the-armaturethat its poles shall be over said arma ture, and means of passing acurrent of elec- .tricity IlJIOLlgll the coils of said magnet as will befurther described.

2 ltt'urther consists in certain novel constructions and arrangements ofthe parts, which will be best understood b reference to the descriptionof the drawings, and to the claims, to be hereinafter given.

0 Figure 1 of the drawings is a side elevation of the pump with the caseiti section. Fig. 2

is a vertical-section on linemw on Fig. 1, and

. Fig. 3 is a plan of the commutator-spring.

A is a metallic casing, intended to be sub- 5 merged or partiallysubmerged in the water of a well or other source of supply, and withinwhich is supported, near its upper part, the pumping apparatus,constructed and arranged as follows:

4.0 [A suction-pipe, 1 3, is firmly secured in an opening in the bottomof the casing A, and projects a short distance below said casingbottomand upward a distance about. equal to three-fourths of the height ofsaid casing, and

has firmly secured to its upper end the receiving-chamber O, composed ofcasting a, provided with the upwardly-projecting annular lip or wall a,the double-flanged diaphragm I), and. the disk c, provided with thedownwardlyproject-inglip c, all secured together by brazing orotherwise, so as to form acomplete chamber which shall be air and watertight, except as hereinafter mentioned.

The suction-pipe B is provided with an inletvalve, d, and the chamber 0is provided with a discharge orilice, communicating through thedischarge-valve 6 with the pipe I), which projects downward from thechamber'G, but does not reach the bottom thereof. The valves 01 and eare preferably of rubber, and of that kind resembling the mitrahvalve ofthe heart; but any other well-known hydraulic valve may be used, ifdesired. The suction-pipe B also supports an electro-magnet composed ofthe coils E and E, arranged upon opposite sides of the chamber 0 and inupright positions, the upper ends of their coresfandf being bent inwardtoward each other at right angl s to that portion within said coils, sothat their ends lie just above the upper surface of the iron armature F,secured to the upper plate or disk, 0, of the receiving-chainber O in ahorizontal position. as shown in Fig. 1, said cores being madein onepiece with the horizontal harf as shown; or they may be made separatetherefrom and set in sockets formed therein in a Well-kn0wn manner.

G is a U shaped stiff spring-frame, between the upper ends of which issprung the commntator'spring H, so that it shall assume a slightlyellipticalshape, as shown in Fig. 2, the center of said spring H havingriveted- "fillereiil a platinum contact-point,g, which projects uponeither side of said spring a short distance, as shown, said spring beingprovided at each end with short projecting lugs g g, which embrace theedges of the spring-frame G, to prevent lateral displacement of thecommutator-spring H, which is also prevented from being displacedvertically by notches formed in the inner faces of the upright portionsof the spring-frame G, into which the ends of the spring H enter, asshown in Fig. 2.

Upon the upper side of the upper horizontal portion of'the coref aresecured the metal con tact-plates h and hf, which are insulated fromeach other and project inward, one above and theother below thecommutator-spring H, as shown in Fig. 2. The under side of the plate 'his faced with platinum and connected with one end of the wire of thecoils E and E, the opposite end of said wire passing out through theplug I, of hard rubber or other suitable insulating material, set in thebottom of the casing A, and is connected by the wire 6 to one pole ofthe battery J, the opposite pole of-said battery being connected by thewire j to the metallic frame of the pump.

L is a portion of the pipethrough which the water is discharged from theinterior of the casing A, said pipe extending upward to the point whereit'is desired to deliver the water.

The operation of our invention is as follows: The parts being in thepositions shown in the drawings, if the circuit be completed by con-.

meeting the wires 7: and j to the battery, the current of electricitywill pass through the coils E and E, magnetizing the coresfa-ndf, whichattract the armature F and move it,'with the disk 0, upward till thearmatureis in contact with the under surface ot'said cores, the flangesot' the diaphragm springing sufficient to permit such upward movement,and thus increase the size of the receiving-chamber O, which tends toform in said chamber apartial vacuum, the result of which is the openingof the valve d and the admission of suflicient water to destroy saidvacuum. The upward movement of the armature F'and the upper head of thechamber 0 causes a corresponding upward movement of the spring-frame Gand ot' the two ends of the commutator-spring H, and as its center isalready in contact with the plate h.'and cannot be moved upward, it ismade to assume a curve the reverse of that shown in the drawings, andits contact with the plate h is broken, thus destroying the circuitthrough the coils E and E, when, the coresfand f no longer attractingthe armature, the chamber 0 contracts by virtue of the reaction of thespring-diaphragm b, and causing the valve 6 to open and water to bedischarged through the pipe D into the interior of the casing A, fromwhich an equal amount is discharged through the pipe L. The contractionof the chamber 0 causes the center of the commutatorpring H to be againthrown in contact with the plate It by the plate It, preventing adownward movement of the center of said spring, thus closing the circuitand causing the armature F to be again attracted and moved upward by themagnet, which operations may be repeated indefinitely. The stroke isshort; but as the area of the disk 0 is many times larger than that ofthe suction-pipe B, and as the strokes are repeatedat the rate of, say,one thousand a minute, it follows that a considerable quantity of watercan be pumped in the course of an hour. p

The casing A, inclosing the pump, serves the double purpose of anair-chamber to equalize the pressures and to enable the pump to besubmerged and still be operated in'air.

We do not in this application claim broadly the commutator composed ofthe spring H, spring-frame G, and contact-studs hand It, as this isclaimed in a separate application filed as a division of this case. j,

What we claim as new, and desire to secure by Letters Patent of theUnited States, is

1. In an electric pumping apparatus, the combination of a reoeiving-chamber composed in part of expansible side walls, an armature secured tosaid receiving-chamber, an electromagnet, meansot' causing the passageof a current of electricity through the coils of said magnet, andsuitableinlet and discharge'valves for controlling the flow of water toand from said receiving-chamber, substantially as described.

2. The combination, in an electric pumping apparatus, of the casing A,provided with the discharge-pipeL and the inlet-pipe B, a pump locatedwithin said casing, near its top, and communicating with saidinlet-pipe, an electromagnet for operating said pump, and a commutatorfor controlling the current of electricity, both located in said casing,and a battery located outside of said casing and connected by suitablewires with the magnet within said casing, substantially as described.

3. In an electric pumping apparatus,the combination of the chamber (J,composed of the castings a and c, and the doubleflanged diaphragm b, thearmature F, an electro-magnet, the spring frame G, the commutatorspringH, and the contact-studs h and h, all arranged and adapted to operatesubstantially as and for the purposes described.

4. The combination of the chamber 0, composed in part of thedouble-flanged springdiaphragm b, the armature F, secured to saidchamber, the two coils E and E, located upon opposite sides of thechamber 0, the coresff of said coils having their upper portionsextending toward each other over the armature, as set forth, thespring-frame G, the commutator-spring H, the plates h and It, secured toone of the cores f or f, but insulated from.

each other, and suitable inlet and discharge valves for controlling theflow of water to and from the chamber 0, suhstantiall y as described.Executed at Middlebury, Vermont, this 10th day of February, A. D. 1882.
